What is a likely consequence of improper curing on surface quality?

• A. Improved surface texture
• B. No effect on surface quality
• C. Decreased curing time
• D. Increased cracking, dusting, and reduced long-term strength.

Answer: (D)

Improper curing disrupts the hydration process by letting the surface lose moisture or experience unfavorable temperatures, so the outer cement paste doesn’t hydrate fully. That leaves a weaker, more porous surface that is prone to cracking, dusting (surface powdering), and reduced long‑term strength. Proper curing maintains moisture and appropriate temperature to allow continuous hydration, producing a smoother, stronger surface.
